IP Lookup WHOIS: Find the Location, ISP and Owner of Any IP
Use this free IP lookup WHOIS tool to see who owns an IP address and roughly where it is. When you open the page it runs a public IP lookup on your own connection, or you can enter any IPv4 or IPv6 address. You get the approximate location, ISP, organization, ASN, timezone and reverse DNS in one place.

IP geolocation is approximate and usually accurate to city level at best. If you are on a VPN, this shows the VPN server, not you.
What does an IP WHOIS lookup show?
An IP WHOIS lookup tells you which network an IP address belongs to: the internet provider (ISP), the organization the address block is assigned to and its autonomous system number (ASN). CyberScop adds the approximate location, timezone and reverse DNS, so you can see who is behind an address in seconds.
| Result | What it means |
|---|---|
| IP version | Whether the address is IPv4 (for example 203.0.113.42) or IPv6. |
| Location and continent | Where the address is registered or used, usually accurate to the country and often the city. |
| Coordinates | The center point of that area. It is not a building or a street address. |
| Timezone | The local time zone of the IP location. |
| ISP | The internet provider that carries traffic for the address. |
| Organization | Who the address block is assigned to, such as a company, a university or a hosting provider. |
| ASN | The Autonomous System Number of the network that announces the address on the internet. |
| Reverse DNS | The hostname linked to the IP, if one is set. Mail servers usually have one; home connections often don't. |
Need the full registry WHOIS record, such as the address range or abuse contact? Look the IP up at the regional internet registry that manages it: ARIN (North America), RIPE NCC (Europe, the Middle East and Central Asia), APNIC (Asia-Pacific), LACNIC (Latin America and the Caribbean) or AFRINIC (Africa).
How to use the IP lookup tool
- Check your own IP. Open this page and the public IP lookup runs on your connection automatically.
- Look up another address. Paste any IPv4 or IPv6 address into the box and press Look up.
- Read the owner details. The ISP, organization and ASN show who runs the network. The location shows roughly where it is.
- Take the next step. Use Copy to save the address, or check whether it is a VPN or proxy with the VPN & Proxy Checker.
Public IP lookup: what websites see about you
Every website you visit sees your public IP address. From it, a site can estimate your country and city and see which internet provider you use. Your public IP is shared by every device on your home Wi-Fi, while each device also has a private IP (often starting with 192.168 or 10.) that only your local network can see.
If you're connected to a VPN, the public IP lookup shows the VPN server's address and location instead of yours. That is a quick way to confirm your VPN is working. To check that your browser isn't leaking your real IP in other ways, run the DNS & WebRTC leak test.
Website IP address lookup: how to find a site's IP
This tool looks up IP addresses, not domain names. To find a website's IP address and see who hosts it:
- Run a DNS lookup. Enter the domain in our DNS Lookup tool and choose A (IPv4) or AAAA (IPv6).
- Copy the IP address shown in the A or AAAA record.
- Paste it here and press Look up to see the hosting provider, ASN and location.
Many websites sit behind a content delivery network (CDN), so the IP often belongs to the CDN rather than the site's own server.
Can you track an IP address's exact location for free?
No. Free IP location tools, including this one, show an approximate location: usually the city or region where the internet provider registers the address. They can't show a street address or a person's name. Only the provider can match an IP to a customer, and it normally does that only for a legal request.
| Location detail | How accurate it usually is |
|---|---|
| Country | Usually correct |
| State or region | Often correct |
| City | Sometimes correct, sometimes a nearby city |
| Street address or person | Never available from an IP lookup |
Mobile networks, satellite internet, VPNs and company networks can make an IP look like it is in a different city or even a different country.
Why look up an IP address?
- Check where a suspicious login or password-reset request came from.
- Investigate spam, failed-login floods or bots in your server logs.
- Find out which company owns a connection or hosts a website.
- Confirm that your VPN is changing your public IP and location.
- Troubleshoot geo-blocking or a website showing the wrong country.

IP Lookup FAQ
What is an IP lookup WHOIS?
It's a lookup that shows who an IP address belongs to: the ISP, the organization the address block is assigned to and the ASN. CyberScop also shows the approximate location, timezone and reverse DNS.
Can I track an IP address's exact location for free?
No. IP location is approximate and usually points to the provider's network in a city or region. No IP lookup can show a street address or the person using the connection.
How do I look up a website's IP address?
Run a DNS lookup on the domain and copy the A or AAAA record, then paste that IP address into this tool to see who hosts the site.
Can I look up IPv6 addresses?
Yes. The tool supports both IPv4 and IPv6 addresses.
Why is the IP location wrong?
Providers register address blocks in one place and use them in many. Mobile networks, VPNs and company networks make the difference bigger.
What is an ASN?
An Autonomous System Number identifies a network, such as an internet provider or hosting company, that announces IP addresses on the internet. It's useful for blocking or investigating traffic from a whole network.
Does CyberScop store the IP addresses I look up?
We do not keep your lookups against your identity. Standard server logs are kept briefly for security. The Privacy Policy explains the details.
